Using the BZBGEAR BG - USB - LR100 USB 2.0 Extender is a breeze. First, connect the transmitter to your computer using the USB - B port. Then, use a CAT 5e/6 cable to link the transmitter and the receiver. Next, plug your peripheral devices like printers or cameras into the 2 - port USB hub on the receiver. When it comes to power, you only need to connect one of the units (either the transmitter or the receiver) to a 12V/1A power adapter. The other unit will get power through the cable. Here are some things to keep in mind. Make sure to use a good - quality CAT 5e/6 cable for the best performance. Avoid bending the cable too sharply as it might affect the signal. For maintenance, keep the devices in a dry and clean place. If there's dust on them, you can gently wipe them with a soft, dry cloth. That's all you need to know to make the most of your USB 2.0 extender!
